Product Details

This secondary air shut off valve helps to reduce emissions by mixing fresh air with the exhaust. When this part fails cause a engine fault code and it will trigger a "service engine soon" light.

This is also one of the main causes of carbon build-up in the E39 M5 secondary air system. This shut-off valve can allow exhaust gas to blow back into the system where it accumulates. Regular replacement of this part will help prevent that build-up.
